Abstract
The invention belongs to sulfurous iron ore and smelt the sulphur technical field.Utilization sprays into alkaline liquid in tail gas, make the SO that produces in the smelting
2And H
2S gas reacts, and solves problem of environmental pollution, and improves the sulphur recovery rate.
Description
The invention belongs to the sulphur technical field of smelting.
In the existing sulphur smelting technology, adopt earth kiln to smelt in a large number.Because smelting process produces a large amount of SO
2And H
2The S gaseous emission has caused the serious environmental pollution, 10 kilometers place around the stove group, and inch of land is not given birth to.Production efficiency is low simultaneously, the sulfurous iron ore of general grade about 16%, and ton ore sulphur gained is about 4%, " the airtight reduction method of purification " smelting technology of existing document announcement, though the smoke-uptake that just extended is than earth kiln smelting reduction SO
2And H
2The S discharging, but not from basic solution, and investment is bigger.
Purpose of the present invention is exactly in order to overcome the deficiency of above-mentioned prior art, to propose a kind of new refining sulphur Processes and apparatus, making SO
2, H
2The S discharging is up to state standards fully.The sulphur recovery rate is higher than prior art.
Solution of the present invention is: at H
2S, SO
2Before the emptying, increase a reaction chamber, spray into alkali liquid in the reaction chamber, make SO
2, H
2Oxidation takes place and also reacts in S in alkali atmosphere, the sulphur that reaction generates is in thereafter settling pocket sedimentation.
Further specify the technical program below in conjunction with drawings and Examples.
Accompanying drawing one is a process flow sheet.
Accompanying drawing two is reaction chamber, settling pocket structure iron.
In smelting furnace (1) stove sulfurous iron ore and fuel (for example coal) with usual manner stow light after, the H of generation
2S, SO
2, the S(gaseous state) enter sulphur case (3) from leading sulphur pipe (2).In order to make gaseous state S cooling-sedimentation, sulphur case (3) is designed to plural serial stage, and gaseous state S cooling post crystallization becomes solid-state simple substance S, is deposited in the sulphur case (3), for taking out refining.SO
2, H
2S enters reaction chamber (5) through main flue (4).Several shower nozzles (6) are equipped with at the top of reaction chamber (5), and alkali liquid (for example liming) forms vaporific ejection from shower nozzle (6), along with SO
2, H
2S enters settling pocket (8), SO through transition flue duct (7)
2, H
2Redox reaction takes place in S in alkali atmosphere, generate S and H
2O.
S and other impurity are deposited in settling pocket (8), and the seal of regularly opening settling pocket takes out and separates refining.
In order to make SO
2, H
2S fully reacts, and settling pocket is taked plural serial stage, and every grade floss hole (9) aperture position is staggered, makes SO
2, H
2S, vaporific Ca(OH) thorough mixing, planar form movement locus shown in the accompanying drawing (three), form tracks shown in the accompanying drawing (four) in the vertical plane.
The remaining SO that unreacted is intact
2, H
2From chimney (11) discharging, Ca(OH) liquid is from reaction chamber through tail flue (10) for S, water vapour, and the settling pocket bottom is reclaimed and used.
Claims (4)
1, a kind ofly smelt sulphur technology with sulfurous iron ore, comprise smelting furnace, sulphur case, reaction chamber, settling pocket is characterized in that spraying into vaporific alkali liquid at reaction chamber, make H
2S and SO
2In alkali atmosphere, produce redox reaction.
2, sulphur case according to claim 1 is characterized in that taking the above plural serial stage of secondary at least.
3, settling pocket according to claim 1 is characterized in that taking the above multistage tandem of secondary at least.
4, according to claim 1 and 3 described settling pockets, it is characterized in that about every grade of settling pocket floss hole position, about hand over justice to arrange.
